Application filed Dec-camel 18, 1909.

To all whom it may concern."

Be it known that I, RALPH K. Garnish Tr, citizen of the United States, residing at Edgewater, in the county of Bergen and State of New Jersey, have invented certain new and useful improvements in Acetylene- I (.las Generators5 and I do hereby declare the fallening to he a full, clear, and exact do scription of the invention, such as will enable others skilled in the art to which it ape the same, refer-- ence being had to the accompanying drawings, and to characters of reference mar ted thereon, which forn'i part of this specification.

The present invention relates, generally, to an improvement in acetylene-gas generators; and, the present invention refers, more especially, to that class of acetylene gas-generators in which the carhid is fed, in required amounts, into a water-chamber as distinguished from the class of generators in which water is dropped upon the carhid. I

The present invention has for its principal object to provide an acetylene gas generator which is constructed so as to be particularly adapted for use upon automobiles, launches, and all classes or moving vehicles, as well as for many other-uses, wherein a portable acetylene gas-generator may be desired for the purpose of furnishing ,gas for illumi1'1at-' ing purposes. The invention has for its further object to provide novel construction of acetylene gasgcnerator of the class above set forth, which may he suhjected in its use to vibration, such for example as would necessarily upon a moving automobile, launch, or other moving vehicle, without interfering with its perfect operation. To this end, the present invention providesan acetylene gasgenerator which among other novel features, is provided with a novel construction of water-chamber or reservoir having connected therewith an anti-splash device or devices which prevents the water contained therein, when agitated by the vib 'ation of the generator, from entering the carbid storage reservoir, or

being splashed upon parts of the teeth nlechunism for said carh'id, whereby it! could through capillary a dam, or otherwise 'Iatcnted July 11, 1am.

Serial No. 533.748.

in contact with the carhid contained in said carhid storage reservoir, with dangerous or zit-least wasteful results.

perlia ps A further object of the present invention is to promote novel arrangcn'icnt of carhid teeciing mechanism which is automatically con t ated, that the rol led by tile pressure of the gas-generiunount of generated is controlled by the amount of gas consumed;

and, another object of the .inv provide a. i'iovel construction 03. valve through the operation of pressure of the the that the amount of the :ioju' to regulating which the which delivered to and, furthermore, said regulating gas so delivered to the linirner locus may be increased or decreased at will.

Another object of this invention is" to provide in connection with the carbid feed i'nechanism' and reservoir, a means whereby the said reservoir and feed mechanism may be sealed effectually against the entrance of vapor or moisture, when the supply of carid is shut off automatically by tlOXL ot' the feed mechanism, said generator is not in use.

the opera..- or when the Other objects of the present invention not at this time more particularly enumerated will he clearly understood from the following; detailed description of my present in vention.

' With these various objects of my present invention in view, the sists, primarily, in. the

said invention coniiOXel construction of acetylene gas-generator hereinafter set forth a nd,

sists furthermore, this invention conthe several novel arrangements and combinations of, the various devices and parts, as well as 1n the details of the construction thereof, all of which will be hereinafter more fully described in the follow inn specification, and then finally embodied in the clauses of the claims which are appemled to and which form an essential part of this specification.

set forth lene asgenerator, I will lurielly acetylene its operation in generating the gas.

The water-chamliicr 3 is filled with water, the level of said water rising through said funnel-shaped shell 8 until it covers the said tweak-water device formed by the projections it). By means of this arrangement, a small proportion of the water maintained at a point accessible to the falling carbid. The quantity of water. thus cxposethis small that under the action oil vibration or the unstable movements to which the generator may be subjected, when in use, the agitation thereof is not accompanied with great or heavy splashings; the break-water device tending further to prevent sudden and spasmodic splashing or upheaval oi the water from the main resevoin l l hatevcr slight agitation of the small quantity of water may result. in. the funnel shaped shell 8 expends itself in the splash-chambers l4, and does not rise and is not thrown up into the tubular Sillflltlttllig member 20, where it could come in contact with the l ecd-mechanism, and by capillary action, or otherwise, worl: its way into the Clllbid container, where it would act upon the carbid tending to cake the same and prevent its proper feeding. Any splash or gitation of the water, which might tike place, in lateral, lines and not in vertical lines, hence the splasli-chambers let Iill catch the same. As a iliurther precaution the apron iscaused to surround the exposed portions of the feed-mechanisni.

,Thc carhid chamber being supplied with carbid, preferably in small jgi'ani'dai' form, or in small aggregated cry-stills, the genen ator is ready for operation.

hen the generator is not in use the screw+hank it; is screwed upwardl: so that the head ll) bears upon the cap and thereby exerts an upward pull upon the feed mechanism, so that the gate 54- closes the cal-bid outlet 29; and, furthermore, draws up the valve so that it lightly {its upon the seat and seals the opening; a; ainstv the passage the ethrough of gas or vapor.

"When it is lJZSIl'QLldLO start the generator, the

ni -shank 46 is screwed downwardly, leaving the spring 50 free to act. so that the same presses clown the feed-mochanism and forces the gate 54; downwardly, whcrel'iy the outlet 29 is opened to the passage of carbid tl'ierethrough, and at the same time opens the valve-member 55, so that.tl1e carbid drops into the water. The gas beinggener ated by the contact of the carbid with the water, riss and presses through the open fced-mmzhauism into the space (ll, and then passes through said tiller-device and pros surea'einilaling \tllYL. S1) to the gas outlet noezle 8. i
